I don't really think someone scripting Gimp needs lambdas.  And your 
first lambda will fail because 1 is not a function, but you've put it in 
calling context as the first element of a list.

Other than that, "if" is as straightforward as in any language.

(if condition
   this
   that)

or just
(if condition this)

Actually, the "if-then-else" statement was born in Lisp.
