It depends on the kind of turn count you want to reach. Getting below 10k turns requires extreme skills, tactics and luck, below 40k much less so. I would advise to start with a few practice games, where you ask yourself at every step if you could skip doing X and do the next step immediately..
One easy step is to enable autopickup, at least for everything that light and useful like scrolls and potions. At least the last time I checked (years ago), picking up stuff with autopickup did not increase turn count.
P.S. monks are actually pretty good at speed runs if you are aiming at something like <40k turns. Good all-round class and the class power to switch with hostiles can save some turns.

You steal a scroll labelled HITME. The orc hits you.
