Your Rental Income and Expenses are reported on Schedule E, same as a US rental property. If you paid tax to a foreign country on your Rental Income, in the Foreign Tax Credit section, you can enter the amount that you were taxed on by the foreign country (either net or gross income).
If you were taxed on the net income, you don't have to enter expenses. If on the gross income, you can enter the same 'definitely related expenses' that you used on your Schedule E (excluding depreciation).
Here's more info on Depreciating Foreign Property.
