I draw what is being said. Not verbatim, as no one can draw that fast, but capturing the key messages, insights, themes and conversations. I draw on an iPad Pro linked to either a projector or plasma so the entire audience can see the illustration unfold during the course of the session. When drawing live I capture content, with a little measure of wit in there as well. I add colour post event because although colour makes the illustration look awesome, it shouldn't be at the cost of content. More on that under 'what do you get'...
