Concrete suggestions:
1) Making plans to meet outside of work. (e.g. getting lunch, going to an outing in the city, hiking, meeting up for an outside project, etc.)
2) Continuing casual conversation offline / digitally. (e.g. chatting on Facebook.)
3) Opening up, talking about more personal things (e.g. mentioning you had a bad day, slight window into how you’re feeling, let the other person reciprocate)
