The Thing is inspired by At the Mountains of madness, but the only similarities is really the Antarctic setting and the fact that the monster can shapeshift. It's not Lovecraftian.
There's quite a bit more similarities than just the two examples you mention.
ATMOM is a horror sci-fi tale set in the Antarctia where human characters discover the remains of an unidentifiable life form and were badly damaged (Carpenter's The Thing 82 connection: split face, the unidentifiable charred remains).
As the story progresses, it's revealed they were ancient aliens (same as Thing's thousands of years old aliens) and some of the 'remains' come to life without notice from the human characters (connection: the remains of the films and the novella mostly play out the same way).
There's a second human camp in ATMOM, where the main characters go there and discover it has been destroyed and the men have been slaughtered (connection: Carpenter's Norwegian camp).
The dogs of ATMOM were also slaughtered just like the violent attack on Carpenter's dogs. Combine all that with the example you mention of the creatures ability to change form just like Carpenter's film and the novella, that's more than just a vague similarity.
