Hello!
Well it depends on what resources you have available near you and how your network looks like. For example, if you are in touch with people from a local university, you can offer to co-PI on some of their research or consult (depending on your expertise). I have seen several clinicians partner up with university researchers and use that to get back into research. You could also offer to be a guest lecturer to grad courses and build up your network of faculty that way. I've also seen people start teaching as adjuncts for the grad program, and then building up to include some research collabs.
Given your interests in program evaluation and quality improvement, there might be some opportunities at a department-run clinic - maybe they need someone to help implement some outcome based evals of their work, or analyze some data they have been collecting. A hospital or clinic might also be interested in this as well, since it always seems to be on the mind of leadership, but never have the capacity to start anything meaningful in that regard.
Reaching out to a former lab/supervisor might also be helpful in getting back to research as well.
However, I think you have to keep in mind that you will probably have to volunteer your time for many of these opportunities, and that it will add to your current workload without a lot of financial compensation, at least not at the start. From my discussions with clinicians that transition back into research, it seems difficult to find a balance. A lot of times, they reduce their clinical work a lot to take on research work. So this is something else to keep in mind.
