There is an interesting machlokes on how to read the words of רצה. We say והשב את העבודה לדביר ביתך ואשי ישראל ותפילתם באהבה תקבל ברצון. The question is how do we punctuate it. Should we read it as והשב את העבודה לדביר ביתך. ואשי ישראל ותפילתם באהבה תקבל ברצון
or
והשב את העבודה לדביר ביתך ואשי ישראל, ותפילתם באהבה
In other words, does ואשי ישראל go with the first sentence or the second. It is not just a dispute about the punctuation, it is really a dispute about what the words ואשי ישראל mean, the punctuation depends on the meaning.
This is based on a Gemara in Menachos 110 and a medrash. The gemara there writes that the malach מיכאל brings korbanos in heaven every day. The Tur quotes the medrash that this is what the words ואשי ישראל are referring to in רצה. The Tur has another explanation that when there is no Beis ha'Mikdash, our Tefilos take the place of Korbanos. We therefore pray that our Tefilos, which are now the ואשי ישראל, should be accepted. The Gra holds that ואשי ישראל is going on the korbanos that we no longer can bring like one opinion in Tosafos
The bottom line comes out like this.
Both opinions of the Tur - ואשי ישראל goes with ותפילתם because it either refers to tefila, or it refers to the Korbanos that Michael is bringing, in either case we want hashem to accept it b'ahava along with our tefilos.
Gra - ואשי ישראל goes with the previous statement of והשב את העבודה לדביר ביתך as it is referring to korbanos and we are expressing our tefilla to Hashem that the avoda of the Beis ha'Mikdash be restored speedily.
I don't believe that there is any clear psak about this, everyone should follow their minhag. What is important is that a person should always be consistent 1 way, and understand what the words mean based on how he is punctuating it.
I remember that Artscroll takes a stand 1 way (they have to punctuate it), I don't remember which way.
