Talk about them. You should never talk about yourself with someone you like, it's just taboo, and makes them feel like you care more about yourself than them. Talk about their day, how they feel, talk about what they like to do. Talk about what movies and music interest them, and what they enjoy doing in their spare time. Keep the subject light and never talk about things like religion or politics, that is a sure fire way to spark an argument. Just relax, and let the conversation flow, if you try to force it, people can tell right off. Just relax, enjoy the company, and enjoy the talk.
