What was Vasher up to...

[Firespir]

before the events in Warbreaker and after the Manywar?

It's mentioned in the text he couldn't have returned earlier, implying he was in another world until the events of the book. I tried to find any WoB that might reference this but without any luck.

I'm not sure that implies he was Worldhopping, though that is a possibility. We do have this WoB:

Has Vasher ever been to a world other than Nalthis or Roshar, or was this his first time worldhopping?

Brandon Sanderson

Vasher has only been to Roshar and Nalthis, beyond places in Shadesmar.

So, if Vasher was not on Nalthis, he was likely at Silverlight. If he had been on Roshar (with access to Stormlight) he wouldn't have gone thorugh all of the breath he mentions to Vivenna in the epilogue (and probably would not have come back); but the Five Scholars have history with Silverlight, so that could be an option. I always took it to mean he was wandering Nalthis and had just gotten back to this side of the Bright Sea.
