Does anyone have any general tips for this?
Memorization is the key. I played some games blindfold versus some friends of mine - not strong players - winning all them within 40 moves. Some players say that you should play static pawn structures and solid systems like 'Colle System' but this self-limitations can lead to difficoult midgames and endgames if you are not familiar with resulting positions. You should build your own opening repertoire and familiarize with it, its midgames and its endgames. If you already know the ideas of the position it will be easier to play it, tactically and strategically. A good theoric knowledge is an important resource in endgames too.
Analysis skills should be reduced while playing blindfold, but some good training can improve the 'visualization'.
Here are some useful exercises to improve memorization and visualization:
1) re-play all the moves (on a board) of your games without watching annotations and then control the correct move order;
2) try to play games reading only the annotation;
3) memorize diagrams in a book and reproduce them on a chessboard;
4) Play blindfold!
