I have modeled the lumped element circuit for the 3D structure which has been simulated in HFSS. Now I need to derive the equations for the lumped elements keeping the S-parameters of the structure in hand. Is there any standard procedure to do this? If so, please let me know!

You can use this^ paper for reference. I have my personalized codes for extracting R, L, G, and C parameters from two-port S-parameters of transmission lines. If you want, I can share that on Github.
Dear Suhas ,
I think the link below can help you.

I have a unique method that requires the knowledge of interpolation and from the poles derive the required R, L, C equivalent circuit.
From the four set of S-parameters (both real and imaginary), equate them to four set of cauchy interpolation rational function. By moving the denominator over to the know S-parameters and grouping the equations into AX=b, these unknown can be solved by total least square method. Note for the existence of b column matrix, the a0 of the denominator should be set to 1.
After finding the cauchy coefficients for both the numerator and denominator, perform a S to Y transformation and then, factorize both the numerator and denominator into their roots. From the concept of poles and zeros, one can deduce the required optimal equivalent from the concept of Y-parameters.
