Write a one page table of contents for a strong paper that you would like to write
Then do exactly the research needed to fill in the holes in the paper
Then write a detailed outline. In fact, I suggest making slides for a talk and giving the talk to whoever will listen
Refine the slides.
Further refine the slides to make a detailed outline (e.g., one bullet per paper paragraph)
Then write the text. I find that you wind up deviating from the outline in certain local parts
Then put it away and reread it, or give it to colleages to read
