My advice would be philosophical rather than technical.
Women like to know that men respect them and understand that they are capable. Society has traditionally assigned some activities as gender specific, and fishing gets lumped into the list of "manly" things. Women can feel intimidated by the "manliness" of fishing, and are afraid to ask questions or display a lack of confidence.
My best advice would be to make sure you both have a good time, enjoy the outing, and don't worry about needing to stick a bunch of fish to feel good about it. You can work with her to show her some stuff IF SHE WANTS YOU TO, or let her pick a lure or setup, even if it is just because she likes the color. You gotta remember, nothing is as "out of the box" as a raw beginner, because they have not yet built their box.
Encourage her to do a little research on her own, if she is into that sort of thing. If not, then just be supportive and accepting, have fun, and y'all will most likely be planning another bass trip.
All that being said, remember a few things.
Small baits get more bites, most of the time. Some baits work well in what I call "monkey mode" meaning you can teach a monkey to do it. Cast and reel, cast and reel, etc.
Small crankbaits, small spoons, small spinners, small grubs, and underspin/ponyhead type jigs are all fairly good bets. Light line, small baits, if you don't get a couple bites with that type of stuff then there might not be any fish in your spot. I would say you guys take a team approach and fish different baits till someone gets some bites, then zero in on that item. Also, don't set up camp in one spot unless it is rewarding you with bites. Fish a few minutes, fifteen at the very most, then move to another spot. You will catch some fish.
