There are several examples out there that can help you, and you may even want to use as a source. I have included one that a former student created. With font, I generally use around 24 size when it comes to PowerPoint body, using Century Gothic, and I tend to use size 42 for the title. I will not be that picky with the particular style, as long as it is clear and can be read. I also want the font to be uniform, meaning the title is larger and the body should all be the same size and same font. I will deduct points if I am unable to read font.
