Returning to academia after a year in industry
Sure, why not? What you write makes me think that you could tell them exactly the way you tell it here: Being recovered from the PhD and full of fresh ideas.

It is not unheard of that PhD students need to recover from the PhD by doing some different kind of work for a while (such as a couple of years in industry, I've even heard of running a store in a completely different retail sector).
Personally, I think that it should be taken as a warning sign if this happens regularly. However, that consideration doesn't have anything to do with your position, but I think it is worth while remembering when you enter the side of PhD supervisors. 

Regardless of how much enthusiasm you've gained back I think it would be a good idea to sit down and recall what exactly drove you away and what caused you feel (close to) burned out - in order to avoid getting there again. I somehow think it unlikely that a postdoc position would be more calm than a PhD.
