No tools are seriously required for any form of energy manipulation. However, divination requires reading certain things or finding meaning in certain happenings to make predictions. And so, I will explain how to decide for yourself which tools are and are not required.
Most forms of divination have to do with a certain topic or element. For example, tarot will obviously involve tarot cards. The act of divining through tarot involves reading the cards drawn and so no cards means no divination, tarot cards are therefore required.
Other forms include hydromancy, pyromancy, geomancy, and aeromancy to list the four basic elements. Hydro means water, pyro means fire, geo means earth and aero means air. So, naturally, hydromancy requires water to be present, pyromancy requires fire to be present, geomancy requires earth(or earth related objects such as wood or stone) to be present, and aeromancy requires air(most commonly wind) to be present. In these cases it is possible to use an elemental subtype, such as smoke for fire. The subtypes are listed in the element lessons.
There are dozens, possibly hundreds, of other forms of divination, however I trust knowing what you now know your own common sense can guide you with knowing what is required with them. If you come across a divination name that you don't understand and thus don't know what is required, simply remember that "mancy" means "divination by" and so the first part is what is required. You can type that into a search engine to find out what it means. For example, if you type "definition of pyro" when trying to find what pyromancy is, you will find out that it is divination by the use of fire because "pyro" means "fire."
The only other art I have encountered which would require something present is kinesis. You can't control flames without fire, you can't control wind without air, you can't control waves without water, and you can't control plants without earth. Likewise with plain telekinesis you can't lift an item that is not there, so obviously certain things are required with that art.
Some arts, rather then requiring a certain tool, require a partner. As a prime example, telepathy. You can not read nor send to someone who does not exist.
