Here's the card structure that I've settled on for grammar. I'm sure people have done it better, but here's what I have:
front (2 fields):
kanji: 飲みたいなら、レッスンのとき、コーヒーを飲んでもかまいません。
furigana: (only if I need it, here I don't)
back (2 fields):
English: If you want to drink during the lesson, it's not a problem if you drink coffee.
Grammar point: 〜てもかまいません
So basically, when I do English -> Japanese I see both the sentence and the grammar point to use.
