This is my method, it works for me in my room:
Imagine a line going straight up 2-3' from the drummer's head.
That is your vertical center.
The horizontal center is a line going from the ride cymbal or right most cymbal through the hi hat or left most cymbal.
The horizontal line will likely NOT be parallel to the face of the kick drum.
Spread the mics out so that they are 1-3' apart, depending on the size of the kit.
Start with the mics aimed straight down.
Then angle them 10-20 degrees away from each other side to side.
And tilt them 20-30 degrees up towards the cymbals.
This will give you a cymbal dominant sound with the ride and hi-hat in nice balance, and minimal phase issues with close mic'd toms, kick, and snare.
