None are possible without further information from you. Size and layout (diagram preferred) of the room, including any windows or skylights are needed. Otherwise I could say "my bathroom is 8 x 5 and I can't imagine pot lights, and vanity, and even one light fixture in there together!"

If you want recommendations for actual light fixtures, you are going to have to include the material and style of the vanity, tile, rest of the house, and your style preferences.

For a bathroom that large I would want to install recessed lighting or ceiling fixtures for general use, and vanity lighting above or to the side of the mirrors. I would want to switch them separately so that you can walk in and flip on the main lights (general lighting), and/or turn on the vanity lights for shaving, make-up, etc.

Don't forget to plan for and locate switches for an exhaust fan and heater. Its best if they are separated a little from general lighting switches, to avoid the confusion of having 3-4 unmarked/identical switches in one box.
