Next you need an objective monitoring system, and that starts now. For example, you said you have clay, but what kind of clay? What exactly is the SOM content? Ph? How does it vary over different parts of the land? How does the vegetation vary? Have you actually measured it? So start off right now with a good soil test(s). That will give you a baseline to judge the effectiveness of your plan. Then make a map of the predominant vegetation and try to quantify it's density. Again for a base line. You will probably need to actually make assessments in each season on vegetation.
"Permaculture is a philosophy of working with, rather than against nature; of protracted & thoughtful observation rather than protracted & thoughtless labor; & of looking at plants & animals in all their functions, rather than treating any area as a single-product system." Bill Mollison
In permaculture we always think about the crucial role animals play in the nutrient, carbon, water cycles. They can be wildlife, or domestic animals if wildlife is lacking, it even includes small animal impact like insects and worms, but the land absolutely needs animal impact if it has any chance of regenerating in your lifetime. Always remember that.
“As the small trickle of results grows into an avalanche — as is now happening overseas — it will soon be realized that the animal is our farming partner and no practice and no knowledge which ignores this fact will contribute anything to human welfare or indeed will have any chance either of usefulness or of survival.” Sir Albert Howard

One thing. Even a nice dense clay has the potential to turn into sticky gloppy muck with the addition of Organic Matter. It can also form awesome clay loams. Number one thing I think is to have a constant and fairly substantial organic mulch on the surface. Stuff that hasn't decomposed to muck yet. I'd also start toying around with the idea of char but that just me.
