I´d like to -somehow- assign an empty object to drive a procedural texture. The idea is that I can rotate, scale or move the empty and thus it transform the procedural texture (bricks, noise texture, etc..)
How can I manipulate a procedural texture using the position of an empty?
Thanks.
As @moonboots has commented, you've already got it.. and just done a bit too much? This setup puts the texture into the Empty's object space, so transforms on the Empty will transform the texture.
It is often helpful to debug the procedural node coordinates with a setup like 
As x,y,z get mapped into rgb. Here you can visualize the difference between all the different coordinate outputs, as well as check the correct transformation. As moonboots pointed out, the "Object" output works best for what you are trying to achieve.
