Books have been filled with the topic, which is still unsolved to this day. Expecting me to give you a "detailed plan" can't be meant in good faith. At least it seems that way. I can answer your question only in a very boiled down manner: through bottom-up organizing.
I can point you to a direction though. The anarchist FAQ has both the answer to your question in more detail than I could write in a comment. It also a good introductory text.
I also have a video explaining why voting does not help in liberating people.
