Mexican-American?
How would you say a Mexican-American woman?
¿Una Mexicana-Americana?

There is one problem: All Mexicans are "americanos", since in Spanish anyone from Argentina to Canada is in "América". Even though most people know that people say Americans to refer to the inhabitants of the USA, the rest of Latin America also see themselves as "americanos" (if you wonder why, read it again: Latin America).
Anyway, if you insist in saying such a thing, you have to use an accent and avoid the hyphen: méxicoamericana. And do not be surprised if Mexicans say that they all are "americanos".
"México-Americana"
The most concise way I can think of is "una chicana".
