I always find dungeons when I'm lost. and it makes you more familiar with your map.
I tend to not leave caves until I've fully explored. If my inventory fills up early (usually only if I find a dungeon) then I dig up and out, place a chest and a torch marker above ground, and then go back under to continue.
I use a simple two cobblestone and one torch system. I place one cobblestone with a torch on it and then a second in the direction pointing out/back. It's kind of like a compass telling me which way to go should i need to leave or empty my inventory. It works really well in long multi fork caverns where I keep hitting dead ends and have to turn around a lot and back track.
Always put torches on the left wall, then when you are lost any torches on the right hand wall lead the way out.
Exactly what I do. I also mark the forks/main entrances to new areas (or areas where I've already been if I'm leaving and coming back) with two torches right next to each other. Double torches means that's the way out.
