I used to be Wiccan, before I discovered the path that I am on now, so I could provide some examples of the tools I used.
I used a small altar as my workspace. You could get tools to represent each element, such as a wand (most Wiccans believe this represents Air, but some say it represents Fire), a chalice or cup (Water), an athame (Fire or Air), and a pentacle (Earth).
You could also make or buy a small besom, and could get a boline.
Remember, though, don't get too caught up in tools. They're nice to have, but it's possible to work spells without them. You also don't have to buy them. You could get a stick from the woods, sand it, rub it in oil, and use it as your wand, for example.
