Like I wrote back in this post about designing your property with permaculture, step one is "do nothing" - just observe your property for at least a year (if you can), figure out what you want from it and what it can do, then start planning one small project at a time.
When it comes to figuring out what you want and what your property can do, this post about "What to do with eight acres" might give you some ideas (adjust them to fit the size property you have).
If you have more than a few acres, you might find Keyline design useful as well, it helps with placement of roads, fences and water storage on larger properties, by considering the terrain (or keylines) of the landscape.
I find permaculture is the best design tool, you can read my post about David Holmgren's 12 permaculture principles here:
A few books that might help:
