The mathematical structure of thermodynamics by Peter Salamon (pdf) would be an example, but i would like a more abstract natural formulation of application of differential geometry or even geometric algebra to for example Maxwell relations in thermodynamics that does not use coordinates.

There is a calculus textbook which does this:
Bamberg and Sternberg A course in mathematics for students in physics, vol. II, Chap. 22, "Thermodynamics".

In this context, one should probably mention "Contact Geometry: the Geometrical Method of Gibbs's Thermodynamics" by V.I. Arnold (Proc. of the Gibbs Symposium,Yale University, 1989, 163-179).
