One way to do this: Find a system that an alliance has influence over. Click on the Star in that system and then INFO. Then on the INFLUENCE tab. Then click on the Alliance Icon of the alliance that you want to declare war on. This will take you to their alliance details page. Down the bottom right is a DECLARE WAR button.

The "structure" of how a war is conducted is explained elsewhere.

Summary:  1) Get kicked out of each others territory. 2) 12 hours of preparation. 3) 24 hours of being at war. 4) 72 hours of war cooldown with that alliance ONLY.
