I seem to have lost the plot in Skyrim. Literally.

I'd completed finding Esbern and the Karthspire camp and the "Dragon Wall" (or whatever that was), and then Delphine and Esbern buggered off back to Riverwood.

Since then, nothing. No sight nor sound of the main quest.

I've become Thane of most places, acquired houses all over, and am mostly walking the Earth and doing random things.

The only quests I have active are Miscellaneous ones.

Is there a way to somehow get back onto the main quest? I've done perhaps 50%+ of the game and am loathe to start again, but kinda feel like abandoning instead of wandering aimlessly.

Have you gone back to the greybeards? if memory serves you need to go and talk to arngeir or whatever his name is, and after being a bit of a defeatist prick "maybe the world is meant to end" he teaches you a shout that lets you get to the very top of the throat of the world.
