Ask HN: Hosting a baller panel discussion

Hey, I am a data scientist and I work for a large silicon valley tech company. I have been asked to host a panel discussion at a very important company event. My panelists are C & D level executives and most of our major customers will be there. I have some experience with giving presentations to a large crowd, but nothing like this. I am looking for advice on how to host a panel discussion that engages the viewers.
