Surfacing directly under a CV1 (no guns) and recharge, all the while darting left and right to stay inside the CV until you get enough air. After submerge, pull the throttle off and wait for the CV to pull into prime range and drop the necessary quantity of tubes to ensure a drop (never waste torpedoes).
Or surface right next to a Lion II and before he can swing his guns, you pop a smoke and cut to the opposite side and stay on top of him while nursing your wounds and filling your tanks.
PS: don't forget to submerge before the smoke clears...
