We had 8 tables so relay between 1 and 2 and bye stand after 5. The game started and a pair arrive a bit late. Ive hurry to call somebody that live near and I completed the 9th table. Ive pick up the bye stand boards to play them (thinking great they are already shuffled and we wont need them anymore ?!) but completly forgot about the relay. After 3 round ive realized what i have done. So the 3 first round were played with 24 boards instead of 27.

What is the proper procedure for correcting this mistake.

I-m making this up and maybe it won-t work (or it-s too late for the answer to be of use) but you had to stop the tourney make a progression of what-s gonna happen and then realize you-ll have some pairs in the 4th round (and afterwards) encountering the same boards they played on the first round: have them play a different set introduce 25-27 and have it shared between two of these tables. I-m sure there is a solution but it involves bringing a new set, have other tables share boards.

At the round in which some E/W players start to encounter boards they've played before, call a double skip move and if any E/W players still get a set of boards they've played before, have that table play the set you thought you didn't need.

This is how it looks for 4 tables that became 5 - I assume it works OK for 8/9. Not sure if there is a better solution.

This does entail meeting one other pair twice.

N=NS
E=EW
B=Board set

Later edit - er - the solution doesn't seem to scale - so forget this - it works for 4/5 tables only.
