In the PA28 I learned in the technique was:
Good look out into direction of turn - lookout to the other direction - check still straight and level - lookout into direction of turn again - roll on 30 degrees of bank with reference to the horizon over the nose not instruments - throttle to full power - roll on another 30 degrees of bank - maintain altitude using forward and backward movements of the control column. If descending or ascending too much just roll off some bank and get re-established.
Once you're 30 degress from the direction you want to return to straight and level, power back to normal cruise rpm and just roll off the bank.
Worked every time once I broke it down into these components.
