Here's how I got the Automator workflow to work in OSX 10.10.5:
1. Open Automator, select Service, and click on Choose.
2. In the new untitled workflow, set Service receives selected to: "no input" in: "Contacts.app" (in 10.8.5 it may still be called Address Book.app -- find it by browsing for it under "Other...").
3. In the Library (left pane in Automator), click on Contacts.
4. In the Contacts list of actions (next to the left-most pane in Automator), drag "Get Selected Contacts Items" into the workflow (the rightmost pane in Automator) (the action is likely named "Get Selected Address Book Items" in 10.8.5).
5. In the "Get Selected Contacts Items" action, set it for "People".
6. In the Contacts list of actions (next to the left-most pane in Automator), drag "Get Contact Information" into the workflow BELOW the "Get Selected Contacts Items" action item.
7. In the "Get Contact Information" action, set export format to "Formatted Text", and also select the general information you'd like to copy (I used the select all button and then deselected the couple items I didn't want, like birthday, for example). If you want the workflow to first ask you what info you wish to copy from the contact, click on Options at the bottom of the action and set it to "Show this action when workflow runs".
8. In the Library (left pane in Automator), click on Utilities.
9. In the Utilities list of actions (next to the left-most pane in Automator), drag "Copy to Clipboard" into the workflow BELOW the "Get Contact Information" action item.
10. Save the workflow (in the menu File/Save...) and give it a name like "Copy Contact".
11. Open System Preferences and click on "Keyboard" to access the Keyboard system preferences. Click on "Shortcuts" and then select "Services" in the left pane. Scroll down the various services listed in the right pane and locate your saved service ("Copy Contact" if you named it that).
12. Click on the saved service to highlight it, then click on "add shortcut", then type an unused keyboard combination to create the shortcut keystroke (I used the control/option/command keys (all pressed simultaneously) + C key). Close the System Preferences window.
13. That's all for 10.10.5. In 10.8.5, in the Address Book app, with a contact selected, you may have to go to the Address Book menu, select "Services", and select your service to activate it (although I'm not sure that's necessary).
14. Now, in the Contacts application, select/highlight a contact name, and press your shortcut keystroke. The contact information will be copied to your clipboard, which you can then paste into another application (like Word, Mail, etc.).
Good luck!
