Hello,
I was veneering a panel with some red oak veneer, clamping between chipboard cauls and using yellow glue. The glue bled through the pores in the oak and appeared on the top surface. How can I prevent this from happening?

Doug,
You can't prevent wet glue from penetrating the open pores of a wood like red oak if the veneer has no backing. Actually, you can't really prevent it on many other veneers that have finer structure than red oak.
Solutions are to 1. use a veneer with a backing. 2. Use a glue that is not the problem that PVA glues are (use hot hide glue, then just sand away the excess). 3. Apply PVA to the substrate, allow it to completely dry, then "iron the veneer down" with a hot iron, activating the dry glue with heat.

This bleed through will usually sand away fine with no problems. I prefer to use urea formaldehyde glues for my veneer work and i actually want some bleed through. It is a sign that I have enough penetration.

As Rich said, use hide glue, then sand away.
