The one tip I can give, from the receiving end of teaching, is to make sure you know how to use your presentation equipment. Thoroughly.
After my first lecture with a particular professor, I had to go up to the front and explain to him how to switch his laptop's DOS box to full-screen, so that the (old) projector would get a bold, readable font to display instead of the very lightweight Courier New. The DOS box was what he was using to demonstrate how to run the Java compiler.
I hear of people not even knowing how to convince their laptop to put a signal on the external video port. So if in doubt, take your stuff and your laptop's manual to an empty lecture theatre and try it out. If it might be needed, make sure you can access the network and any fileservers from there too.

) and managed to get done in record time. There were only a few people in line when I showed up, but the folx at the counters all had that vaguely harried look to them.
