I don't think there is
a best way to do it. It will be an adapter/converter mess any way you try it, with not so great picture quality.
They make powered HDMI to RCA/RGB adapter boxes (a simple cable/dongle does not work well because of the digital->analog downscale needed or vice versa). The picture quality passed through a bunch of adapters and a box like this one will degrade your signal quality a lot. Not to mention the opportunity of running into other issues like HDCP (copy protection) issues and PAL vs. NTSC problems if you are not in the U.S.

You will be trying to push the signal through this mess:
Phone w/ HDMI via Micro USB out -> Micro USB input into powered MHL adapter w/ 'full' HDMI Out -> 'Full' HDMI input to powered adapter w/ RCA/RGB output -> RCA/RGB input to SCART output -> SCART input on your TV
If you have a basic computer monitor with a VGA input on it you might find it a little easier to use than an old TV with SCART. This cable might work a little better, though I have no experience with it.

The One is MHL compliant so you should be able to plug this cable right into the phone, though you may end up needing another adapter MHL to Micro USB. It is not be clear to me if it will work directly.
Also the image from the phone will be a 16:9 output to a likely 4:3 monitor, the edges of your picture may be forced off the viewable screen. You may still need an audio adapter or a VGA M/F converter depending on your situation.
