You can use the ABM model "LAPLACE", which allows specification of a transfer function in the s-domain.

try ELAPLACE part from ABM library. Modify EXPR & XFORM parameters. XFROM is your transfer function.
You can also write the your expression directly in CIR file, Following is an example:

ERC 5 0 LAPLACE {V(10)} = {1/(1+.001*s)}
