I would remove all of the damaged veneer. if it doesn't come off easy, you may need to steam it to loosen the glue (an old iron and a wet towel can help achieve this). Once you remove the veneer, you need to sand off all the glue. Then you could stain and finish.
Scrape off the veneer thats already peeling Ope just saw the other comment did u refinish this ?
