On softer materials I use doweling. Sharpen the doweling in a pencil sharpener (one of those pre computer gadgets with the crank handle). A dab of stamp pad ink on the point will leave an exact mark.
Another one of my tricks is to cut off a piece of one of those stick erasers (I keep several diameters around) put it in the hole and again use a stamp pad refill bottle to apply ink.
If you really need an accurate mark cut off a piece of all-thread or just the threads on a screw. Take your bench HFT drill press and drill down the center of the threaded shaft just big enough to put a small finishing nail in the hole, (hot glue may be required). A tap with a plastic or rubber hammer will leave a nice dimple to start drilling at.
