How to subtly show interest in a guy via text?

I really like this guy and he's admitted to having a huge crush on me in the past but I don't know if he'd still feel that way. I want to make it clear that I'm interested without just outright saying it and coming on too strong. How should I go about doing it? What should I look for in regards to whether or not he's interested. We're only texting right now since we haven't got a chance to see each other in person for a while.
