I'm not a consultant myself, but I've known a lot of people in this industry who have gone into consultancy.
The most important thing is that you know more about the subject than the people you are hoping to work for. That means years of experience and relevant training courses.
I'm not sure that a PhD will do you any good unless you can find one that is extremely relevant. It's 3 or 4 years out of your life in which you could have been gaining practical experience in industry.
The usual route I have seen is to work in the industry as a normal employee until you have gained enough experience, then leave and set yourself up as a consultant.
