What are the suggested procedures in Tennessee for opening these accounts? Do we setup a trust record on our system with an EIN, or just add the trustee and beneficiary with SSN? Who should we CIP? Thanks!

This article says that you must use the beneficiary's SSN. There are others that say the same thing.

If you are not familiar with these sort of accounts, you might want to have a chat with your legal counsel.

Who you would CIP would be governed by your board approved CIP policy regarding trust accounts.
