You lucky, lucky lad. I'd love to be able to set up my own personal hide somewhere.
Firstly, study the ways of the animal that you're intending to photograph and find out what sort of habitat it likes, what it eats, what time of day is best and obviously if one has been seen you've got a good start.
On the day you set up, be sure to wear clean clothes that haven't been washed in any kind of perfume and be sure that you don't wear any yourself (deodorant, aftershave, hair gel etc.). If you smoke, then learn to go without - they'll smell you a mile away (just like we can).
Be sure to make sure you are always downwind of your intended target (wind coming from them to you) this will greatly reduce your chances of being detected. Wear broken pattern clothing similar in colour to the surroundings so that the outline of your body isn't easily recognised (camo gear can help if you have it).
You need to be as quiet as possible - noisy shutters may even spook them, so if you can use an electronic shutter it could help.
If you see any road kill en-route, pick it up to use as bait as it will attract any meat eaters. Be sure to place it on a high spot, so it won't be hidden behind grass etc. from your hide.
A few sticks or poles and camo netting is better than a pop-up IME - these work, but only after the animals have got used to it being there.
Good luck, we look forward to seeing your pictures.
