This response is based on the information provided.  We suggest you discuss with your contracting team, program manager and/or legal department as appropriate. 

We are not exactly sure of the aspect of "HOW" you are wanting answered. 

DFARS 237.7204 presents a generic format which falls along the lines of a basic ordering agreement.  If your "HOW" is more related to creating a deal, that is market research and the art of negotiation.  You will need to identify what you want the potential contractor to provide and see if it exists in the marketplace.  If it's out there, your team would define the details using the DFARS format or similar and let industry know.
