Xerces has a fact sheet on building beetle banks.

They also have lists of native plants by ecoregion that may be helpful to you.
Pollinator-Friendly Native Plant Lists | Xerces Society
Another source for Ohio natives:
Native Plants Lists | Ohio Department of Natural Resources (ohiodnr.gov)
A local chapter of the worldwide Wild Ones organization may be able to provide a lot of help:

And lots of on-line resources, including lists of native plant nurseries can be found here:

Your imagination is the limit on building habitat--sounds like a really fun project. If you have more specifics on your property (urban with HOA, rural, somewhere in between) and the type of habitat already present on your property (wooded, pond, meadow, etc) I might be able to come up with other suggestions.
Beetles are an extremely diverse group of insects. Their dietary habits range from scavenger, to carnivorous, with the larval stage often being different from the adult stage. Most of the larva are either scavengers or herbivorous. Many of them nest in or actually eat decaying wood, so I would recommend including some wood in your bank. (It sounds as if you are not in an area with a Homeowner's Association checking up on your yard.) Some beetles are pests (eg Asian Longhorn Beetle), some are well-known beneficials (eg Lady Beetles).
If you are planning on attracting beetles for their benefits to a garden--pollination, pest control, debris break-down--you will want to keep your beetle habitat close to the garden. Many of the predaceous beetles hunt close to home.
Decomposing plant matter such as spoiled hay, rotting logs, and compost piles are excellent beetle habitat and can be included in the beetle bank. The plants you use will attract a wide variety of insects, some of which will be prey for the beetles. While you are attracting beetles, you will also be providing habitat for many other insects, including native bees. As I said, increasing biodiversity is a good thing.
Waiting a growing season to see what is already in place is a good idea. Keep notes also about the amount of shade, moisture, and general soil type. This will help you chose the right plants for the right place. Your "vernal pool" areas sound like natural spots for a rain garden or mini-wetland area. (Some beetles are aquatic, too!)
Sounds like a fun project, as long as you have plenty of energy.
Below are some additional resources about building beetle banks. I will admit I had never heard the term before you asked this question, but it fits right in with my gardening philosophy. Now I may have to build one too!

Good luck with your project, Donald. Sounds like you have your work cut out for you...every spring I bless my sandy loam soil. I believe there is a survey at the bottom of the signature line on the form via which I replied if you want to give feedback.
