Here are the things I "reset" before each time I head out... I keep this in my head but at first I had to think about it more:

• Mode dial set to your preference (P, Aperture Priority, Shutter Priority, etc)
• ISO set to your preference (usually low)
• Memory card has been formatted (assuming it's been downloaded)
• White balance set to auto
• Auto Exposure Bracketing turned off
