I am installing plastic laminate on a cork underlayment. I just found out all I have for a subfloor is one layer of 3/4" plywood which I have to remove ceramic tile grout/adhesive from. What would be a good solution for adding more subfloor? Luan? CDX? AC plywood? What thickness? Thanks

The old tile is history. I need to remove it and scrape the adhesive up then apply the new underlayment.

Why remove the old tile floor? If the old tile is still tight and not coming up. Just go over with the cork underlayment, and then the laminate. If the old tile is coming up in places, then you must remove. If you get lucky and the tile comes up clean with out much damage to plywood. Again just go over with the cork and laminate. If If you tear the plywood to level only use thin plywood, if you need the extra strength go thicker 1/2"

If you have a 3/4" subfloor, it depends on what other floors this floor will be abutting. For instance. If you have a tile floor that is usually 1/4" tile and 1/2" CDX plywood and sitting on the 3/4" subfloor, this will be even with the 3/4 hardwood flooring. The only time I use luan is if I am putting down vinyl flooring as luan is made of mahogany which has a chemical reaction to tile adhesives and is not recommended.
Good Luck.

if the tile is solid you can install the laminate over it. it may be a little higher but they make reducers to make up for it. a sub floor is part of building a house which would be 3/4 in plywood or osb. a substrate is what you put down to adhere a floor to. it would be rather odd that your tile is installed directly to your sub floor. the movement it would have would cause the tile to pop.

if your present floor is level and sound , i wood just go over it with a 1/2in. plywood, most laminates state in there instruction that a 5/8in. or better subfloor is recommended.

depending on where you live you can buy cc underlayment rated plywood and go with 3/8" thick that will stiffen your floor and you will make it more quiet to walk on follow your instructions on your laminate
