I wipe down the bike before putting it in the car/taking it into the house. I take everything out of the seat wedge and top-tube bag so I can dry it all out.

I clean and lube the chain before I ride it again.

I stuff my shoes with newspaper or paper towels, replacing it every few hours until the shoes are dry. Remove the cleat covers, clean and lube the cleats.

That's pretty much it.
