1. Actually come up with a theory of Intelligent Design. It must make positive, testable predictions beyond "Evolution is wrong, therefore Intelligentdesignerdidit." It must make predictions of the form "if intelligentdesignerdidit, then when we perform experiment x, we will observe y." Observing something other than y must disprove the theory of Intelligent Design.
2. Perform experiments. The results of those experiments must not be explainable by the theory of evolution, or by any other explanation other than an intelligent designer. In the course of these experiments, you must make a concerted effort to conclusively disprove that an intelligent agency had any hand in the creation of life, and for every single experiment, there must be a result predicted which would disprove the action of an intelligence.
3. Repeat step 2. A lot.
4. Publish the results obtained in a peer-reviewed scientific journal.
5. Repeat steps 2-4. A lot.
6. Sit back, relax and enjoy a beer, and keep your Nobel prize polished to a healthy shine while ID is automatically inserted into science textbooks everywhere, and becomes the new standard in science education in biology.
Do these six things and no scientist on earth will object to ID being inserted into science class. Evolution has done this many times over. That's why it's in science textbooks right now. If ID did the exact same thing, it'd be in the science texts within the next 20 years, easily.
So, who's up for it?
