Mary, I've found keeping track of information that tends to vary class to class is most helpful to me. For instance, terms, formulas, facts, comments are the most frequent. I also track observations about students, questions, changes needed or wanted, and any issues that arose during class. Less frequently, I'll enter information that's intangible, such as desired equipment, ways of adding to or modifying the curriculum, or observations about student behavior or why things are done how they're done.
