Your typical monastery would indeed have various cottage industries. You could probably break it up into: those parts of the monastery associated with worship/religion, the parts associated with daily living, and the parts associated with industry, probably to raise some money.

The other thing that matters a lot is how isolated they are - if they are miles from the nearest village, they'll need to make most things for themselves. If, however, there's a village at the bottom of the hill, they can probably make do with much less. Remember, the traditional monastic life was meant to be humble, so you don't want to start cramming the monastery full of things they wouldn't have. I personally doubt a smelter and smithy would exist, for instance, as it seems a bit too specialised. What are they smelting? Do they have their own source of ores? If so, presumably means they are also running a mine, and the whole thing starts to sound more like a village than a monastery.

If this was a Christian monastery, you would expect:
- at least one cloister (for quiet contemplation)
- church (fairly obvious, really); churches also come with all sorts of different parts (eg chancel, westwerk, aisles, naves etc.); again, that's for a Christian monastery, so yours might be different.
- chapel/s (eg. if the monastery receives financial support from someone, such as the local lord, a wealthy merchant, even the king, that person might want the monastery to include a chapel to their patron saint). Chapels were common in monasteries; most monasteries would be devoted to at least one saint anyway, so would need to have a chapel for that saint somewhere (often attached to the church building)
- tombs: again, this is for a Christian monastery, but it was quite popular to be buried in a monastery, as it was sacred ground. Therefore, lords and kings might want to be buried in the monastery (perhaps look this up; I know it did happen, but I don't know how common the practice was). You would definitely need somewhere for the monks to be buried/cremated/eaten/whatever method is used
- reliquary: having a relic (eg the finger bones of Saint So-and-so) made a monastery wealthy, as pilgrims would come to visit; again, I don't know how common this was.
- chapterhouse: this, as I understand it, was basically the meeting hall for the monastery; apparently in Christian monasteries it would be located on the eastern wing of the cloister, although I don't know why
- refectory: self-explanatory
- kitchens: self-explanatory
- dormitories: self-explanatory
- infirmary: pretty self explanatory; some monasteries might have been set up also as hospitals, but, if yours is at the top of a mountain, that sounds unlikely
- gardens: as Talondor said, fruit and vegetables would be present (fruit trees have the additional benefit of not having to be on level ground, so you could have the orchards on sometimes steep slopes down the mountain). There would also be herb gardens (for food and medicine); fish pond seems plausible; I don't know about melon patches, but it's possible.
- guest houses: if you have pilgrims come to stay (especially if they are rich pilgrim) the monastery would often have a guest house or two to let them stay.
- administrative building/s

The thing about having cottage industries is that, monasteries live a busy life, and there aren't likely to be too many in the first place. That means you probably couldn't have more than one cottage industry (two at most), and so they'll be highly specialised. Historically, monasteries might be involved in book-making/illuminating, brewing, healing etc. The reason a cottage industry would exist is to make money, also, so if they already hav a good income (eg from pilgrims visiting a relic) then they might not bother with cottage industries. I'm a bit doubtful that they would not only translate/copy books but also go to the trouble of making their own vellum, inks, etc. They have to buy some stuff, like the gold for goldleaf, so wouldn't they just buy vellum/parchment/ink etc as well? As I said before, if I was working on this I would be very careful not to cram it too full of stuff. And as I always recommend, a simple google image search for 'monastery' will give a pretty good idea of what they usually possessed.

Good luck with it, though.
