Banamine 1cc per 100 lbs - pain med (not used more than 3 days in a row)
Long Acting Penicillin 4cc per 100 lbs (every other day or once a day depending on problem)

Those are the basics. Depending on if you get into breeding is whether you have stuff like Oxytocin and Estrumate on hand.
I'd say to verify those doses with your local vet but apparently you don't have that option. The dosages for the wormers may be different in your area.
I also think there is some sort of internet forum for vets on alpacas. I know my alpaca vet is on one of them. They could really answer any questions for your vet.
