I can't find anything to talk about while recording my gaming videos?

Talk about your plans for the channel, what you're doing in Minecraft, your video plans, your plans for other games to play… Your general plans for everything (not including personal things, unless you want to), maybe how long you think you'll continue the series, what you think you'll do next, and things that you are about to do on Minecraft. If you're trying to be humorous, maybe try making up some songs about whatever it is you're doing at that moment.
