Your examples are all wrong, because you can't literally translate tour of Dresden to Tour des Dresden. It has to be Tour durch Dresden or Tour in Dresden.
Die Tour durch Dresden wird (von mir) geplant.
The tour of Dresden is planned (by myself).
Die Tour durch Dresden wurde (von mir) geplant.
The tour of Dresden has been planned (by myself).
Die Tour durch Dresden ist (von mir) geplant worden.
The tour of Dresden had been planned (by myself).
Please note there is no direct portability of tenses either, so the second and third example are an approximation. German Perfekt isn't a present tense but a past tense.
