The easiest way is probably to re-ask a question you were just asked. If someone says "How's your job going?", then you can answer and ask, "Well, how is YOUR job going?" Also, try and remember things you talked about the last time, so you can bring them up again. If someone was waiting to hear something important the last time, you can begin with, "So, did you ever find out about that thing we talked about last time?" People often forget what they talked about before, so this is a good way to get things going in a way they'll be enthusiastic about.
