You often receive radio updates, but more often you don't. So you'll have to do it yourself...
You should shadow a convoy from the edge of visibility to estimate its course and speed. Go slow and turn your smallest profile in order to avoid detection. Going deck awash also helps (setting the depth to 7m in order to have most of your hull under water).
Once you know its course, move beyond visual range and get ahead of it as fast as you can. You can plot the estimated position of the convoy on the map, based on its course, speed and time passed since the last contact. Convoys tend to change course, so it's usefull to check on it once in a while, either visualy or by hydrophones.
Once you're ahead of the convoy, change your course towards it. Try not to be directly in front of it, but slightly to one side. Idealy 2-3 km away from the nearest column.
When the convoy gets in a visual range, dive and maneuvre slowly (silent running on) to get to firing position. Watch out for the flanking escort - she can sometimes sail 1km from the nearest column, and every now and then she can wonder off, searching for subs.
Have your periscope up as little as possible. After you fired your last torpedo, dive silently as deep as you can.
Early in the war (until cca mid 1941) you should try surfaced night attack. It's much easier and much rewarding. You are much more maneuverable, and you can get up to a kilometar from a ship, without getting spotted.
