I wouldn't "try" too hard. Just be honest, trustworthy, and straight-forward with her.
She'll probably have questions about operational stuff (how attendance, procedures, etc) works, where things are (the reliable copy machine, extra this and that), and who to go to for what (introduce her to office staff, counseling staff, etc).
If you feel comfortable, I've always appreciated knowing a bit about the way the politics work. Go to this person for this, but not for that, ignore this guy, he's nuts... stuff like that. She might be afraid to ask you outright.
I've had great and awful mentors in my day. The best ones were laid back, cool-headed, open and available, honest, and trustworthy.
The worst one was always "watching" me, lecturing me, guarded, judgmental, condescending, and wasn't trustworthy. I got rid of her in a hurry. She caused me more stress than help.
Now when I mentor a new teacher, I try to be like the good ones I had. I am also generous with materials and lesson plans. New teachers have very little, and might appreciate a little something. But I'm not pushy about it. I put my files in a public folder, and tell her that it's there if she wants it. If I have extra stuff (posters, materials, etc), I'll leave it in our office and let her know that she can help herself.
PS - T.i.f.f.a.n.y --- I don't know what the rules are in your state, but in MI, you can log your mentoring hours, as well as those workshops, towards PD. Anything school improvement outside of the school day that isn't mandatory.
