How to be dominant?

How do you be dominant in the bedroom? I see majority of people here loves being submissive. My husband always takes the lead even though he LOVES being submissive, I just never gave it a chance. He's been working really hard lately and I want to surprise him by being dominant. I've tried looking it up but I didn't really get the answers I was looking for. We aren't really into hardcore stuff and choking is a no no is our relationship.
