1) Know what you're presenting extremely well. This includes thinking about what questions people may ask, then seeing if your presentation can preemptively answer those questions. 2) Don't just talk. Have a point, something like a thesis, then reiterate that point often without mindlessly doing so. 3) Record yourself practicing and then watch/listen closely for where you think you can improve. 4) Assume that most people aren't revolted by you or immediately thinking you're awful. Most people are forgiving with a couple stumbles or mistakes, as long as your talk is interesting.
