You could start small - ask her if she'd like to grab a cup of coffee or ice cream with you...
Second first date with my husband and I when we started dating 10.5 years ago was dinner and a movie (I was 17, he was 19). First first date was also dinner and a movie (I was 15, he was 17). But we also worked together throughout that period of time and talked in person pretty much every day, that's why I suggest doing something small.
Depends on how old you are as to what you can do. Bowling was another date the husband and I went on - had a great time. Could just be something as simple as hanging out at the other persons house - rent a couple of movies.
