The first step should be familiarising yourself with the permaculture design process. Here are a few links that might help:

these are the David Holmgren version.
Once you've worked through the above (it won't take long), there are various ways of working through the design process. There are various acronyms to help remember them, and
OBREDIM is a popular one:
* Observation allows you first to see how the site functions within itself, to gain an understanding of its initial relationships. Some recommend a year-long observation of a site before anything is planted. During this period all factors, such as lay of the land, natural flora and so forth, can be brought into the design. A year allows the site to be observed through all seasons, although it must be realized that, particularly in temperate climates, there can be substantial variations between years.
* Boundaries refer to physical ones as well as to those neighbors might place, for example.
* Resources include the people involved, funding, as well as what can be grown or produced in the future.
* Evaluation of the first three will then allow one to prepare for the next three. This is a careful phase of taking stock of what is at hand to work with.
* Design is a creative and intensive process, and must stretch the ability to see possible future synergetic relationships.
* Implementation is literally the ground-breaking part of the process when digging and shaping of the site occurs.
* Maintenance is then required to keep the site at a healthy optimum, making minor adjustments as necessary. Good design will preclude the need for any major adjustment.
Sorry this is rather brief, and doesn't go into all the detail of how to actually create the design. You may well find more by searching the web. I'd need to spend more time than I can manage at the moment going into more detail.
