make a list of things you've talked about doing whether together or separately and ask her, too,(roadtrip, midnight bike ride, picnic, skydiving, swimming with dolphins, etc.) and write them on little pieces of paper and put them in a bowl and randomly draw out one and do one for every month you're together. make sure they aren't all really expensive things to do so you don't break the bank.

however, for your first month, you could make a list of all the major places you had your couple-ness (first kiss, first date, where you first met her, etc.) and visit each of them. and if it's not too much to ask, you should tell her how much she means rather than trying to do it with a gift. good luck!! http://geschenkideengenerator.de/geschenkideen-fur-freundin/
