For hinges, I put the hinge where it will go, then trace the inside of the holes with a sharp pencil, taking care to hold the pencil upright, so as not to bias the circle. Then by eye, I judge where the centres of the little circles are, and mark with an awl. What I do next depends on how meaty the wood is. For thin walled boxes etc., I'd use a brad point bit, and put the central spur on the marked centre. For thicker stock or rougher work, e.g. door hinges, I'd mark with a centre punch and use a twist bit, which self-centres in the conical depression left by the centre punch.
