Long Diamonds, weak hand 9+ HCPs, 4 cards of Spades, Hearts stopper Long Spades, Slam Force 9+ HCPs, Hearts stopper As you will see from the table above, cuebid after Lebensohl is a Stayman promising stopper. But if the overcall suit is Club then the cuebid after lebensohl will be made by bidding 4 Clubs so there will be no return to 3 NT. So a different approach is needed here. Most of the players use double to 2 Clubs overcall for stayman with stopper at clubs. So nothing else changes and 3 Clubs cue-bid means stayman without stopper at clubs.

After a minor overcall to 1NT openning, responder may show 5-4 or 5-5 major distribution. Bidding majors at second or third level is possible and shows weak and strong hands, so bidding major after Lebensohl could be used to show 5-4 major as in the below table.

If the overcall is in the third level, then the shifting suit by the responder at the same level is 1 tour forcing. For the minor suit overcalls cuebid could be taken as Stayman but the major distribution should be at least 5-4.
