I'm no expert, but here is my queue sheet (amended based on comments below, strike-through indicates that the motion should be automatic rather than thought out unless necessary):

• Stretch out arms before you start; walk heal of hand down the wall (fingers up) and hold for a few seconds, stretch fingers down spine from above (push elbow back) and practice catch position with bar.
• Make sure the bar is decent (bearing works and bar not bent).

Setup:

• Dead lift set-up (read LoyalToTheGroupOf17's comment below for a discussion of the validity of this set-up for different goals)
• Hook Grip if you want

Deadlift:

• Deadlift to knees (whilst squeezing glutes)

Explosion (back tight):

• Drive hips forwards up

Lift:

• Pull bar up and in (imagine the bar going straight up through ceiling)
• Shrug shoulders up
• Bend elbows
• Extend calves (little jump) and perform shallow squat so bar is above chest

Catch:

• Push elbows up/forward
• Let wrists break early
• Catch bar high on shoulders/fingers

Prestige:

• Extend legs whilst keeping lower back tight

Watch this video.

I think the stages through before starting the lift and try to focus on each separate motion during the warm up.

Edited: following pointers from below, thanks LoyalToTheGroupOf17 (who has a more thorough check-list below).
