Don’t worry about talking about yourself. That is a mistake. Tell her that you want to spend the time with her to get to know her better. Ask her what she likes to do in her free time, ask her what her ambitions are, etc. You can get much broader than that, but those are just examples.
IMO, most men always want to talk about themselves, however, that is a big turn off for most of them. I suggest you flat out tell her thank you for hooking up on the date, because you have always found her to be a smart beautiful woman and you wanted the opportunity to learn more about her.
