The grout lines still match up; I just need a good adhesive to put back on. I don’t want to scrapes old mortar or grout out if possible.

Get some of the Loctite Power Grab construction adhesive.
This stuff grabs pretty good but you'll need to clamp it, prop it up, or duct tape it in place until the adhesive hardens, Good luck
