In addition to the advice and adventure recipes detailed here, reading other adventures is a great way to get ideas, whether they're published adventures or ones your friends have written. You can borrow ideas and structures if they work for your game and tweak as needed.
You don't need to go into the same level of detail you'd see in a published adventure. You might be able to get by with just an outline, some bullet points for each NPC, a breakdown of encounters, and a few rough maps. Or maybe for your style of running games, you prefer to have some text written about each scene, or even particular lines of dialogue. If you're creating your first adventure, it can be good to write out a little more than you need. Just keep in mind that things might change in play.
