I am a pastor, so I make a presentation at least weekly in addition to teaching anywhere between one to three classes a week. Here are my suggestions:

• Know your material well enough to not need any notes.
• Look at the faces of the people you are speaking to. If this is hard, look in between their faces.
• Never look down or look at notes after asking a rhetorical question. Look at your audience and wait a couple of seconds. This little trick helps an audience feel as though they were personally asked the question.
• Speak conversationally as though you were only talking to one person, but speak loud enough and annunciate well enough so that people can understand you. If not, they tune you out. (I subscribe to your podcast, Merlin, and this won’t be a problem for you).
• Don’t talk to fast. Look like you are enjoying yourself. No one will ever feel better about a presentation than the person giving it.

Good luck. I hope this helps. 43F has been a huge help to me.
