Hi .. Im 173 cm tall and weigh 58 kg.... I wld like to lose 2-5kg... what do u think of my plan?

I already walk everyday and run some nights, play with my daughter, clean, swim, just got a trampoline, do yoga and love to be active so excersise is not a problem, I have decided to be stricter with my diet..... Do you think I should be able to lose the extra kgs and still get all neccesary nutrients by eating, fruit smoothie for breakfast with seasonal fruit, half a cup of soymilk, tblspoon of yoghurt.................. lunch will continue to consist of cooked vegetables or salad or wholemeal pasta or rice or cous cous or noodles............................. and for dinner I will have a healthy cereal with soymilk or wholemeal toast with honey and desert is a cup of non-caffinated chai tea with 2 raw sugars and soymilk maybe a lil more honey............. I also add a small amount of cashews/pinenuts/maccadamia nuts or peanuts to my lunch....... oh and tuna or chicken sometimes as well..... Im just missing lentils yeah??/ and I use extra virgin olive oil when I cook........ any ideas to improve this or good tips u know,,,,,,,,,, and if IM thirsty i will drink water...........................
