Just like with any other pointing dog, use birds. Don't make it complicated, get some pigeons and press on. I also would put the dog and you on a program for pointing dogs, whoa,here, more whoa. There are a # of programs out there that work, Hickox comes to mind as a pretty simple method, or Rick, Ronnie, or Delmar Smith's method.
In the past few years we have had a few pointing, labs, goldens, etc show up at out training group. At first these owners expected special "pointing Lab treatment" like pointing was something special. We incorporated them in to the group as if they showed up with a setter and it worked.
I am not a fan of the pointing lab but, I do see their place in the hunting scene. I guess I am lucky, Labs that flush and setters that point and taught to work together including honoring each other.
Good Luck and remember to Teach, Train, Test, and Hunt!
