Avast does an android version that comes with antivirus/anti theft.
Not quite a keylogging feature, but it is pretty darn good for what it can still do.
Oh...and its free...
avast! Free Mobile Security | Antivirus & Anti-Theft App for Android mobile & tablet
avast! Anti-Theft features:
App Disguiser
After downloading avast! Anti-Theft, user can choose a custom name that disguises the app (e.g. call it "Pinocchio game") so that it is even harder for thieves to find and remove.
Stealth Mode
Once anti-theft is enabled, the app icon is hidden in the app tray, leaving no audio or other trace on the target phone ? the app is 'invisible', making it difficult for thieves to detect or remove.
Self-Protection
Extremely difficult for thieves to remove (especially on rooted phones), Anti-Theft protects itself from uninstall by disguising its components with various self-preservation techniques. On rooted phones it is able to survive hard-resets and can even disable the phone's USB port.
Battery Save
Anti-Theft only launches itself and runs when it needs to perform tasks. This preserves battery life and makes it very difficult for thieves to shut it down.
SIM-Card-Change Notification
If stolen and a different (unauthorized) SIM card inserted, the phone can lock, activate siren, and send you notification (to remote device) of the phone's new number and geo-location.
Trusted SIM Cards List
Establish a 'white list' of approved SIM cards that can be used in the phone without triggering a theft alert. You can also easily clear the trusted SIM cards list, to leave the one present in the phone as the only trusted one.
Remote Settings Change
A setup wizard guides the user through the installation process on rooted phones by either writing directly or by generating an update file. No command-line knowledge is necessary to install Anti-Theft rooted. Also supports upgrading the app.
Remote Features
Remote Siren
Option to sound a loud siren, which returns always to maximum volume if thieves try to silence. This siren sound can also be customized (e.g. record own siren sound or select siren sound from file).
Remote Lock
To protect your data, phone can be locked remotely and then cannot be accessed again without entering the password specified by the user.
Lock Phone Settings Access
Enables remote locking of the phone's App Manager and/or phone settings.

Remotely send a customized message to locked or non-locked phone display (e.g. with a reward for its return).
Remote Locate
Remotely locate phone via GPS, WiFi, or mobile network ? for maximum accuracy. Can locate either once or continuously (GPS can be auto-enabled on all rooted phones or non-rooted phones from Android 1.6 to 2.2).
Remote Memory Wipe

Remote Calling
Remotely have the phone call you elsewhere with screen blackened, so that thieves cannot see it. This way you can listen to the phone's surroundings.
Remote Forwarding
Remotely activate/deactivate option to forward or copy call data and/or SMS messages to another device. Call data goes to remote device, but not the call itself. SMS messages, however, are forwarded in their entirety ("CC" copies also to original device).
Remote "Lost" Notification
Remotely send a "Lost" command to trigger same actions as SIM card change (e.g. phone lock, siren, or USB lock). "Found" command deactivates "Lost" command.
Remote SMS Sending

Remote Restart
