Hard thing to judge really, but much like with dating a woman, don't make yourself seem too keen. Unlike with a woman, you can be more honest about your intentions.
If it was me I'd leave the door open, without being too specific. Something along the lines of saying it was a good night, let me know when you're up for it again, I'm free most Tuesday afternoons (for example). It hints at forming another meet up without explicitly coming across as "please spend more time with me I am lonely oh god."
I find in most friendships there is a natural dynamic where one party does most of the setting up, not all the time but just due to them being a more active type or whatever.
